Hello,
I have this configuration where a single master builds the Solr index and it
replicates to two slave Solr instances. Regular queries are sent only to those
two slaves. Configurations are the same for everyone (except of replication
section, of course).
My problem: it's happened that, in a particular query, I expected spellchecker
to give me a suggestion. Fact is that only one of the two instances answers as
I had expected! I checked the data directory and discovered that the failing
instance had a data/spellchecker directory almost empty (12 KB against 7 MB of
the other working instance). I don't understand this behaviour.
I tried to issue a spellchecker.build=true command, and this is what I've got:
